Air suction silencer and compressor

Abstract

The invention discloses an air suction silencer and a compressor, which are used in the compressor field. The air suction silencer comprises a casing, wherein an air inlet and an air outlet are arranged on the casing, the air inlet is arranged on the side wall of the casing to avoid the top end of the casing, and oil leakage holes of the casing are arranged at the bottom of the casing. A guide pipe is connected between the air inlet and the air outlet, and the bottom pipe wall of the guide pipe is provided with an oil leakage hole of the guide pipe. The compressor, including the suction silencer described above. By arranging the guide pipe, the bottom pipe wall of the guide pipe is provided with the oil leakage holes of the guide pipe, and the bottom of the casing is provided with the oilleakage hole of the casing. When liquid lubricating oil enters the air inlet of the silencer, the silencer can separate the sucked lubricating oil and discharge the lubricating oil outside the silencer, thereby ensuring that liquid impact can be effectively avoided, and reducing or avoiding the adverse influence of the liquid impact on the compressor. At the same time, the air inlet avoids the topend of the casing, so that the temperature of the refrigerant sucked through the air inlet is lower, and the cooling capacity and the efficiency of the compressor are improved.

Description

technical field [0001] The invention is used in the field of compressors, and in particular relates to a suction muffler and a compressor. Background technique [0002] With the improvement of people's living standards, more and more family cars are equipped with car refrigerators. There are strong bumps when the vehicle is running, and there is a large angle of inclination when going uphill or downhill. Therefore, the compressor used in the car refrigerator must consider avoiding the occurrence of liquid shock. When the vehicle bumps or goes up and down, if the lubricating oil enters the cylinder of the compressor through the air inlet of the suction muffler, it will cause liquid hammer. Liquid hammer will cause quality failures such as compressor valve failure, poor start-up, etc. Contents of the invention [0003] The object of the present invention is to at least solve one of the technical problems in the prior art, and provide a suction muffler and a compressor, whi...
